The Influence and Optimization of Structural Parameters on the Contact Performance of Electrical Connectors
Contact resistance is one of the main factors that directly reflect the contact performance of electrical connectors.In or-der to study the influence of the four structural parameters of the male and female terminal interference,the width of the reed,the length of the cantilever of the reed,and the thickness of the reed on the contact resistance of the leaf spring electrical connector,the contact resistance of the electrical connector is established based on the Hertz contact theory.The theoretical calculation model of ABAQUS is used to simulate and analyze the contact resistance.An orthogonal experiment is designed to optimize the four structural parameters of a certain electrical connector,and the significance level of the influence of the four structural parameters on the contact resistance is obtained.The test results show that among the four structural parameters of the leaf spring type electri-cal connector,the length of the cantilever beam of the reed and the thickness of the reed have more significant influence on it;and the interference of the male and female terminals and the width of the reed change linearly with the contact resistance.The length of the cantilever beam and the thickness of the reed and the contact resistance show a parabolic change;the contact resistance is reduced by7.52%after the structural parameters of the electrical connector are optimized.
